Diagnostic methods and systems based on urine analysis

A computer-implemented method for diagnosing a body malfunction, the method comprising:

• monitoring and detecting at least one change in urinary parameter values, the at least one change being indicative of the body malfunction, wherein one of the urinary parameter values comprises an oxygen level in the urine;
• monitoring a volumetric urinary output of kidneys using a urine flow monitoring apparatus having a low flow metering device with a microprocessor, wherein the urine flow monitoring device further comprises a negative pressure tube which provides a continuous flow of urine through at least a portion of the urine flow monitoring apparatus;
• determining, using the microprocessor, whether a change exists in a volume value of the volumetric urinary output and a trend of the corresponding urinary parameter value during a predetermined period;
• receiving signals from a plurality of electrodes connected to the urine flow monitoring apparatus, the signals representing the urinary parameter values;
• comparing, using the microprocessor, at least two occurrences of the trend of the received signals at an identical iteration during the predetermined period;
• measuring, using the microprocessor, whether the change of the trend in at least two consecutive time periods exceeds a predetermined threshold in the urinary parameter values received from at least one of the plurality of electrodes;
• and
• detecting, using the microprocessor, the body malfunction based on the determination of the change in the volume value of the volumetric urinary output, and the compared trend change of the corresponding urinary parameter value detected by the received signals during the predetermined period,
• wherein the oxygen level is detected with an electrode from the plurality of electrodes.
